KF25B Datasheet Very Low Drop Voltage Regulators

Manufacturer: STMicroelectronics

Overview: .. KFxxB Very low drop voltage regulators with inhibit.

General Description

The KFxx series are very low drop regulators available in SO-8 package and in a wide range of output voltages.

The very low drop voltage (0.4 V) and the very low quiescent current make them particularly suitable for low noise, low power applications and specially in battery powered systems.

A shutdown logic control function is available (pin 5, TTL patible).

Key Features

  • Very low dropout voltage (0.4 V).
  • Very low quiescent current (typ. 50 µA in OFF mode, 500 µA in ON mode).
  • Output current up to 500 mA.
  • Logic-controlled electronic shutdown.
  • Output voltages of 1.5; 2.5; 3.3; 4; 5; 8 V.
  • Internal current and thermal limit.
  • Only 2.2 µF for stability.
  • Available in ± 2 % accuracy at 25 °C.
  • Supply voltage rejection: 70 db (typ. ).
  • Temperature range: -40 to 125 °C.
